- the cam shaft H, which is put into operation 11 Claims.

This invention relates to remote controls for selective automatic. phonographs, and has for its primary object to' provide an improved remote control whereby any desired selection or a plurality of selections may be paid for and selected at a remote position with respect to the phonograph.

A further object of the invention is to provide aremote control adapted to select recordings to be played and adapted to put the phonograph into operation by means of radio frequency impulses.

A further object of the invention is to provide an improved remote control for phonographs having an improved switching mechanism, whereby an appropriate number of impulses of radio frequency may be transmitted correspond ing to the recording selected.

after each record is played and is latched out The escapement member I8 carries an armature Other objects, advantages and capabilities of the invention will appear from the following description of a preferred embodiment thereof, taken in conjunction with the accompanying drawings in which:

Fig, 1 is an elevational view of a phonograph adapted to be controlled by my remote control;

Fig. 2 is a diagrammatic view and wiring diagram of my improved control elements on the phonograph;

Fig. 3 is a similar diagrammatic view and wiring diagram of a control unit;

Fig. 4 is a diagrammatic plan view showing elements of my remote control unit; and

Fig. 5 is an elevation of the clockwork and associated mechanism of Fig. 3, as viewed from the lower side of that figure.

Referring to the drawings, the improved remote control is illustrated in connection with the multi-selective automatic phonograph known and' extensively sold throughout the country as the Symphonola, the phonograph being manufactured by J. P. Seeburg Corporation of Chicago. It will be understood, however, that the invention may be applied to other well-known The automatic phonograph shown in the drawings is so well known that it need not be. described in detail. It is sufficient to note that it comprises a plurality of manually operable selector levers It], a motor H, and a main switch 12. When the main switch I2 is closed, the motor operates and the record changing cycle becomes operative. It may be noted that the record changing operations, and the accompanying actuationof the turntable (not shown) and the a record. Means'are provided, adapted to cooperate with the selector levers it, so that the record corresponding to an actuated selector lever I0 is moved out and played when the motor II is put into operation.

The main switch I2 is normally open, being maintained in open position by .means of a pin IE on a ratchet wheel l6. lThe ratchet wheel I6 is biased away from switch closing position of the pin l5 by means of a spring 41. An escapement member I8, mounted on a pivot 59, is arranged to co-operate with the ratchet wheel I8.

20, which is adapted to be attracted by an electromagnet 2i. energized momentarily, the escapement member l8 is oscillated so that the spring I} may move the ratchet wheel through ,a distance corresponding to one tooth. This movement of the ratchet wheel'withdraws the pin 85 from the main switch l2 so that this switch closes. The closing of the main switch sets the motor in operation. If the electromagnet 2| is energized a plurality oi'ttimes, then the ratchet wheel I6 is moved by the spring I1 through a distance corresponding to a similar number of teeth. The cam shaft 14 carries an arm 22 upon which is pivotally mounted a striker member 23. This striker member co-operates with a stationary anvil 24. The arrangement is such that after a record has been played, the striker member 23 is moved by the cam shaft 14 until it clears the anvil 24, whereupon the striker member, under influence of the spring 25, strikes the ratchet wheel l6 and returns it toward initial position through a distance corresponding to onetooth on the ratchet wheel.

It is to be understood that if a certain number, for example three, selector levers Ill are depressed and the electro-magnet 2| is energized three times, then the phonograph will be put into operation so as automatically to play the three records corresponding to the three selector levers. When the playing of the third record is finished, the main switch I2 opens and the opplayer arm l3, are performed by a rotation of operator to perform these operations from any When the electromagnet 2| is practical position desired, and in any degree of remoteness from the phonograph.

The mechanism upon the phonograph provided for the purposes of my invention comprises a radio receiver 26, which is tuned for reception of a definite radio frequency. The receiver 26 is provided with an antenna 21. The receiver may be of any desired internal construction, it being merely necessaryto provide an output adapted to close a switch 28 each time that an impulse of the aforesaid radio frequency is received by the antenna 21. The switch 28 is in series with the battery 23 and with a solenoid 30. The armature of the solenoid is'connected to a slidably mounted member 3|, which carries a dog 32,

which is biased towards a ratchet wheel 33. The

member 3| is biased away from the solenoid by a spring 34. It will be noted that when the sole noid 30 is energized, the member 3| moves towards it, the dog 32 slipping past the teeth of the ratchet. wheel 33. When the solenoid 30 is tie-energized, the spring 34 moves the member 3| away from the solenoid and its dog moves the ratchet wheel 33 one tooth.

The ratchet wheel 33 rigidly carries a wiper arm 35, which is adapted to engage an arcuate series of contacts 36 during the rotation of the ratchet wheel 33. The ratchet wheel 33 and wiper arm 35 are biased towards the zero position of the wiper arm by means of a spring 31. This position is determined by suitable stops 38, one of which is stationary, the other being mounted on the ratchet wheel. The contacts 36 correspond in number to the number of selections for which the phonograph is adapted. In the present case that number is twenty. These contacts are ar-v ably mounted member 3| is moved towards it, an

abutment 39 engages an arm 40 and displaces it to its full-line position'in Fig. 2, tensio'ning the spring 68, which drives delay clockworkmeclianism 4| during the return of the arm 40. This arm 40 is mounted on, and operatively connected to, the clockwork mechanism 4|. The arm 40 is connected to this clockwork mechanism by means of a slipping clutch (notshown) ,which may be of any suitable known type, the connection being such that the arm 40 may be moved towards the solenoid 30 without aflecting the clockwork mechanism, but it reverse movement is delayed and made gradualby its'operative connection to the clockwork mechanism. Consequently, the arm 48 is moved to the left (Fig. 2) by the abutment 33 rapidly, but its return is relatively slow and gradual. When the solenoid 30 is energized in rapid succession, the arm 40 is arm 40 is elevated out of contactwith the do 42 during the series of energizations, and the dog 32 moves the ratchet wheel 33 through a distance corresponding to five teeth thereon and moves the wiper arm into engagement with the fifth contact 36. The dog 42 holds the ratchet wheel 33 and the wiper arm 35 in this position until the clockwork mechanism 4| returns the arm into a position in which it actuates the dog 42 and removes it from the ratchet wheel 33. Just before the dog42isdisengaged from the ratchet wheel 33, an insulated arm 44, rigidly connected to the arm 40, makes engagement with a stationary contact 45. After this contact is made and after the clockwork mechanism 4| moves the arm clear of the stationary contact 45, the dog 42 is removed out of engagement with the ratchet wheel 33 so that the ratchet wheel 33 and the wiper arm 35 return to normal or initial position.

Each contact 36 is connected to an individual solenoid. 46 arranged for co-operation With the corresponding selector lever I0. These solenoids 46 are connected to a common wire 41. This wire is connected to the electromagnet 2|, the other side of this magnet being connected by a conductor 48 to the arm 44. One side of the battery is connected by a conductor 43 to the stationary contact 45. The other side of the battery is connected to the wiper arm 35 by conductor 50.

Each solenoid 46 is provided with an armature 5|, which is biased upwardly by a spring 52. Each armature 5| is connected to a hook member 53,

which is adapted to overhang the corresponding selector lever Hi. It will be understood that when a solenoid 46 is energized, its armature 5| moves downwardly against the action of the spring 52, and that the hook member 53 engages the corresponding selector lever III and moves it downwardly. When the solenoid 46 is deenergized, the

40 spring 52 moves the armature 5| and the hook maintained at its highest position until the series of energizations ceases.

When the arm 40 is in its normal position, it'

engages a dog 42 so as'to hold this dog out of engagement with the ratchet wheel- 33. The dog 42 is biased toward the ratchet wheel 33 by a I member 53 upwardly so that the selector lever It may be returned to initial position by the automatic operation of the phonograph.

The operation of the mechanism described above is as follows: When the receiver 26 receives a certain number of impulses, for example five impulses of the appropriate radio frequency, the switch 28 clo'ses momentarily five times. The solenoid 30 is energized five times. On the first energization of the solenoid 30, the arm 40 moves towards it and the arm 44 is moved past the stationary contact 45. It is to be noted that the engagement between the arm 44 and the contact 45 has no efiect because the wiper arm 35 is in zero position and out of engagement with all the contacts 36. During the series of actuations of the solenoid 30, the arm 4|| remains substantially in the position shown in Fig. 2. The five actuations of the solenoid 30 move the wiper arm 35 step by step until it is in engagement with the fifth contact 36, the dog 42 being rendered operative upon the first movement of the sliding member 3| to the left. "The actuations of the solenoid 33 having ceased, the arin 40 returns relatively slowly towards its initial position, bringing the arm 44 into engagement with the stationary contact 45.

A circuit is now completed from the battery 23,-through conductor 50, wiper arm 35, the fifth contact 36, the corresponding solenoid 46, conductor 41, electromagnet 2|, conductor 48, arm 44, stationary contact 45, and conductor 49. Thus, the' corresponding selector lever, that is, the fifth selector lever III, is displaced downwardly and the ratchet wheel I6 is moved into posiwill now move out and play record number five. After this record is played, the cam shaft I4 is put into operation and the striker member 23 returns the ratchet wheel I 6 to initial position, thus opening the switch I! and bringing the operation of the phonograph to an end.

If, during the playing of the fifth record, another series of impulses, for example three impulses, were received by the receiver 26, the third solenoid 46 would be energized and the third selector lever It would be displaced downwardly, and at the same time the electromagnet would be momentarily energized. In this event, the completion of the playing of the fifth record would not stop the phonograph. The fifth record would be returned to the stack and the third record would be moved out and played. It will be understood that the actuation of the ratchet wheel l6 by the striker member 23, after the playing of the fifth record, would not open the switch, since the two actuations of the escapement member i8 resulting from the two series of impulses would have moved the ratchet wheel it two spaces away from switch closing position. Of course, it will be understood that any number of, or all of, the twenty selections may be selected and played before the phonograph stops.

It. will be understood that the series of impulses referred to above and which actuate the mechanism previously described are produced by one or indeed any number of remote control units, the structure and operation of whichv will now be described.

My improved remote control unit may suitably be contained within a housing. (not shown) which is provided with a coin chute 54, .which chute is provided with a switch 55 which is adapted to be closed, in known manner, by an inserted coin.

-One side of this switch is connected to a battery 56, the other side being connected to a solenoid The solenoid 51 is connected to the other side of the battery 56 so that the solenoid 51 is energized each time a coin of the appropriate denomination is inserted in the coin switch as. My remote unit is provided with a series of buttons 58 corresponding innumber to the number of selections for which the phonograph is arranged. These buttons are available to the operator, projecting through the wall of the housing. Each button '58 is mounted on a rod 59, mounted within the housing for axial movement. Each rod is 'tion to open the switch l2. The phonograph sleeve 84 is provided with a left-hand abutment 66 and a right-hand abutmenti'l. It is to be noted that the first sleeve 64 need not be provided with a left-hand abutment and that the last or twentieth sleeve 64 need not be provided with a right-hand abutment.

Each left-hand abutment 66 is located immediately in front of and in overlapping relation to the right-hand abutment of the sleeve El immediately to the left. Consequently, when one button is pushed in, its sleeve 68 is moved rearwardly and all the sleeves to the left of the actuated sleeve are moved rearwardly so that the switch 65 corresponding to the actuated button is closed, and all the switches 65- to the left of that actuated sleeve are closed. All the sleeves to the right of the actuated sleeve remainin their normal position and their switches remain open. The sleeves 64 are biased forwardly by weak pressure, which may be suppled, for example, by

the adjacent leaves of the switches 65. Consequently, the sleeves 64 are returned to normal position and their switches 65 are opened when the bar 62 is again raised. For'the sake of simplicity, it may be noted that if button number five is pressed inwardly, then the first five switches 65 on the left are closed, the other switches 65 remaining open. The switches 55 have one side connected in series and to one side of the battery. The other side of the battery is connected to a transmitter 69. The other sides of the switches 65 are connected individually to an arcuate series of contacts 10, these contacts, of

course, corresponding in number to the number of records in the'phonograph, in the present case twenty.

The contacts it are adapted to be engaged by a wiper arm 1 l, which normally occupies a zero position beyond the contacts. When the wiper arm TI i in normal position, it engages a rocker arm 12, which controls the switch l3, this switch being open when the wiper arm H is in normal posi*- tion. The wiper arm ii is mounted on a shaft 14, which is biased to the initial position of the wiper arm by means of a spring ti coiled around the shaft. The shaft idcarries a gear 15, which is in mesh with the quadrant it. This quadrant biased outwardly by a spring 80 and each is provided with an annular projection 6|. A fingered bar 62, which is pressed downwardly by a spring 63, is adapted to co-operate with the annular projections ti. when one of the buttons 58 is pressed inwardly; this annular projection 5i raises the bar 62 against the action of its spring Consequently, any other rod 59 and button 58, which may have been pressed inwardly, is 1'6:

When the annular projection 6| of the button now being pressed inwardly moves behind thebar 62, the bar descends and holds the button in its leased and moved outwardly by t spring, as

inward position until another button is pressed.

inwardly.

Upon the inner end of each rod 59 is mounted a sleeve 64 of insulating material, the innermost end of the sleeve being closed. The innermost to one side of the switch 73.

is pivotally mounted and carries a projecting arm Ti, which is pivotally connected to the armature- 18 of the solenoid 51. It will thus be seen that when the solenoid 5? is energized, its armature it moves upwardly and the quadrant it moves downwardly, rotating the wiper arm in clockwise direction past and beyond all the contacts. After the arm H has passed the contacts, it engages the rocker arm 72 and moves it to the left, closing the switch 73. The shaft is is connected to the clockwork mechanism 79 by a slipping clutch (not shown), so that the clockwork mechanism is unaffected when the arm ii is swung around in back in counterclockwise direction, under the influence of its tension spring 86, the clockwork mechanism is actuated and serves as. a delay means so that the return ofthe wiper arm H is relatively slow. The transmitter 69 is connected The other side of the switch is connected to the wiper arm H. When the switch '73 is closed and the Wiper arm ll is returning to initial position, the transmitter control circuit is completed through the battery, through each closed switch 65 and through the corresponding contacts Hi, the wiper arm H, and the switch 13. Consequently, during the return of the wiper arm H the control graph stops.

circuit of the transmitter 69 is closed a number of times, corresponding to the number of the button 58 which has been actuated. The transmitter 69 is provided with a transmitting antenna, 80, and it is arranged to transmit an impulse of radio frequency energy each time that its control circuit is completed. Consequently, during the return movement of the wiper arm II, a series of impulses of radio frequency energy are transmitted by the antenna 80, corresponding in, number to the number of thebutton 58 which has been actuated. It is, of course, to be understood that the transmitter 69 is tuned to transmit the same radio frequency for which the receiver 26 is tuned.

The operation is as follows: Assuming that the operator desires to play record number five, he pushes button number five, thus mechanically closing the first five switches 65. Then he inserts a coin of suitable denomination in the chute 54, thereby closing the switch 55 and energizing the solenoid 51. The energization of the solenoid swings the wiper arm from its initial position in clockwise direction past all of. the contacts Ill. It

"is to be noted that the engagement of the wiper phonograph, a remote control unit therefor, said remote control unit comprising a series of switches, each corresponding to a record in the phonograph, manually actuated means corresponding to and adaptedto close said switch, and mechanical means connecting said manually actuated means whereby actuation of one of said manually actuated means actuates the corresponding means and all the preceding means of the series to close the corresponding and all preceding switches of the series, an arcuate series of contacts each connected to one of said switches, a wiper arm adapted to move over said contacts, a circuit including said actuated switches and said wiper arm, a radio frequency transmitter connected to said circuit and adapted to transmit an impulse of radio frequency each time the wiper arm engages a connected contact to complete said circuit, a receiver at the phonograph adapted to receive said impulses,

. a stepping relay controlled by said receiver, an

arm movable by said relay to various positions depending upon the number of impulses received by the receiver, electromagnetic means on the phonograph individual to each recording, and

means'for completing a circuit through said arm to one of last said electromagnetic means to coneach of the next four contacts. The circuit is not 1 with the result that the motor II is started and the fifth selector lever I0 is moved downwardly so that record number five is moved out and playedin the manner described above. If, during the playing of record number five, another button 58, for example, the third button, is actuated and a coin is inserted in the chute 54, threeimpulses will be transmitted and the third selector lever I0 is moved downwardly. At the same time, the ratchet wheel I6 is moved through the distance of another tooth away from its initial position so that both records will be played before the phonograph stops. It will be obvious that any desired number of records may be selected in this manner.

It will be understood that any desired number of remote control units may be provided and operated in this manner in connection with a single phonograph unit, all the records selected by all the operators being reproduced before the phono- The phonograph can, of course, be put into operation by actuation of any of the remote control units.

Although I have described my invention in connection with the specific details .of a preferred embodiment thereof, it is to be understood that such details are not intended to be limitative of the invention except in so far as set forth in the accompanying claims.
